Abstract

A rim guard and extension device for disposal on and engagement with the rim of an open container comprising a tubular member provided at its lower end with an annular flange consisting of a vertical internal member for insertion into the container, a horizontal bridge member, a vertical external member for engagement with the bead on the outside of the container; and an upstanding flange extending from the outer edge of the annular flange which forms a catch basin therewith.

What is claimed: 
     
       1. A rim guard and extension device adapted to be removably secured to the rims of open containers, comprising a tubular member provided at its lower end with an integral annular flange extending radially and horizontally outwardly, wherein the upper edge of the wall of said tubular member tapers inwardly, and a downwardly-extending vertical internal member contiguous with said tubular member for insertion into said container and engagement with the inner edge of said rim, said vertical internal member being tapered downwardly and outwardly at an obtuse angle from said annular flange in order to securely engage the inner edge of various rims of slightly different sizes and shapes, and said annular flange being provided at its outer edge with a circumferentially continuous downwardly-extending vertical external member for engagement with the outer edge of said rim, said annular flange being additionally provided at its outer edge with a circumferentially continuous upstanding flange which is contiguous with said vertical external member and forms an annular catch basin. 
     
     
       2. The rim guard and extension device in accordance with claim 1, wherein the vertical external member is provided with an inwardly directed bead at its periphery which snaplocks onto the bead portion at the outer edge of said rim. 
     
     
       3. The rim guard and extension device in accordance with claim 1, wherein the tubular member tapers inwardly and upwardly toward its top. 
     
     
       4. The rim guard and extension device in accordance with claim 1, which is a semi-flexible, unitary, reusable device.
